WEB-COATING: IMACJEEINE.

Application filed December 27, 1922. Serial Ito. 669,262.

To all whom it may concern:

Be it known that I, Pam. Fare, a-citizen of the United States, andresident of the borough of Manhattan, in thecity and State t of NewYork, have invented a new and useful Improvement in Web-CoatingMachines, of which the following is a specification.

The object of my invention is to provide certain improvements in amachinefor coat- M ing a traveling web whereby thefsupply of liquid tothe distributor over which the web is drawn for the ap lication of theliquid coating is automatica 1y cut ofi and the ma chine is sto ped whena predetermined W length of web has been coated, a common manuallyoperated means being employed for starting the machine and turning onthe liquid supply to the distributor.

A practlcal embodiment of my invention is represented in theaccompanying drawin%, in which ig. 1 represents in side elevation amachine for coating traveling webs with my improvements applied thereto.

Fig. 2 re resents an enlarged .detail top plan view of the liquiddistributor. I,

Fig. 3 represents a cross section through the same. 3 Y

Fig. 4 represents an enlarged detail view showing the means forimparting a step by step rotary movement to the control cams.

Fig. 5 represents an enlarged detail top plan of the portion of themachine whic embodies my invention.

Fig. 6 represents a detail view partly in section of one of the controlmechanisms.

Fig. 7 represents another detail view taken at right angles to Fig. 6 ofone of the control mechanisms.

The machine in connection with which I have illustrated my invention isone for building hollow articles by wrapping the coated web around asuitab e mandrel.

The web is denoted by 1 and it is fed around suitable rollers 2 from thesupply roll 3 to the mandrel at, which mandrel is suitably mounted on ashaft 5, driven from the cross shaft 6 by the gears 7 8. This crossshaft 6 is driven from the main drive shaft 9 through the clutch 10,shaft 11, pulley 12, belt 13 and pulley 14:.

The li uid distributor 15 is shown as a horizont ly arranged tubeprovided in its ill) all

top wall with a series of holes 16 river which the web 1 is drawn. Thisdistributor is supplied with the desired liquid, as for instance anadhesive from the supply pipe 17. A manually o erated valve 18 islocated in the horizonta portion of this supply pipe for regulating andopening and closing the supp y of iquid to the distributor. Thishorizontal branch of the supply pipe 17 is also provided with anautomatically closing valve 19, the stem of which is provided with alever 20.

The means which I have shown for automatically closing this valve 19when a predetermined len th of web has been drawn over the distri utorand for stopping the machine at the same time, is constructed, arrangedand o erated as follows A cross sha 21 is driven continuously from theshaft 5 through a sprocket 22, chain 23 and sprocket 24. This shaft 21in provided with an adjustable crank arm 25 which carries a hook arm 26,the free end of which is adapted to engage a toothed wheel 27 on the camshaft 28 for imparting a etc by step rotary movement to the said she t28. This shaft 28 is provided with two cams 29, 30, one for closing thevalve 19 to shut off the liquid supplied to the distributor and theother for disconnectingthe clutch 10 for stopping the machine.

The device for automatically closing the valve 19 comprises a two armedlever pivoted at 31, the upper arm 32 of which is connected by aflexible connection 33 to the valve lever 20. A sprin 34 serves to tendto swing the arm 32 in a irection to close the valve 19. The lower arm35 of this lever is engaged by a in 36, carried by a verticall movablelate 37, the lower end of Whic latch is provided with a pin 38 arrangedto be engaged by the cam 29 after a predetermined length of web has beenfed, to depress the latch 37 against the tension of the spring 39, torelease the pin 36 from its engagement with the arm 35 of the valveoperatlng lever, to permit the lever to rock, to close the valve.

The mechanism for disconnecting the clutch 10 is quite similar to thatdisclosed with respect to the closing of the valve 19 except that inthis instance the upper arm 4.0 of the rock lever is connected by aflexible connection 41 with a clutch operating lever 42. A 43 isrovided, tending to disconnect zmlutch when the arm of the rock lever isreleased by its cam 30.

A common manuall% operated means is rovided for opening t e valve 19 andclosing the clutch 10 for renewing the supply of liquid to thedistributor and at the same time starting the machine, which manualmeans in the present instanceis shown as comprising a hand wheel 44,connected by flexible connections 45, .46 with the upper means forautomatically cutting off the sup-v 7 1y of liquid to the distributorwhen a preetermined length of web has been drawn over the distributor.
